Location Sensitivity - Cell Phone GPS

This is au fond a system to locate the hand-held once fashioning a call to 911. In the mid to late 1990's, many a folk got cell phones simply for the emergency use of being able to call for help all but anywhere. The problem came up once statistics showed that all but 92% of all serious 911 calls, (where the person was simply barely able to do the call), they either didn't cognize wherever they were or was unable to tell the 911 operator wherever they were, or they power not have been able to talk at all. This caused a big concern, 911 operators couldn't do thing but listen to the person on their cell phone as they pass away. The Location Sensitivity system still doesn't activity if you are in an area that only has an analog signal. (Which is the older cellular system of the mid 1990's and earlier). Most metropolitan areas and all interstate freeways are covered by the newer digital service. It's simply once you get out in the middle of no-where, you power end up with an analog signal. Most!

phones wish display the letter "A" in the top right or left corner once mistreatment this system. Check your phone documentation, several phones don't even as have this capability. Which means if you get into one of these areas, you can't do any type of call what-so-ever.

Soon, the Location Sensitivity feature wish probably be offered by the cellular companies as part of their rating plan. Several carriers like Nextel are already taking advantage of this new technology by giving customers a GPS location service on with their business plan. If you don't have this option with your carrier, and you have a Smartphone you can always purchase one of the SD slot GPS units that works with mapping software. The program I've actually enjoyed is Mapopolis, which works great with most of the popular GPS hardware available. And most even as have a voice activation that wish tell you wherever to turn, which is directed through the speaker phone portion of the Smartphones. The ability to have GPS information and mapping on your hand-held wish be a great plus patch traveling.

Back to the Location Sensitivity. I'm simply curious how more the cellular companies are going to charge for such a GPS type service!? I'm sure they're all working hard right now on the new rating plans that we'll have to pay if you don't have the GPS hardware to install on your Smartphone.

When these services become available, they wish only be location based. Another words, most GPS's these days wish actually give you your current altitude and most have a pretty fast refresh rate. The refresh rate is the time between position updates. An example; If you have a GPS in your hand that invigorated three times per second, this would-be be a really acturate reading. Even as if you are drive at 70 miles per hour, the moving map on the GPS wish be able to support up with your actual location. That's an issue the engineers are dealing with on the Location Sensitivity system. It wasn't designed to have any type of refresh rate at all. Once a position has been found, it ne'er was designed to refresh that position. (I guess if you are hurt, and you called 911, you aren't supposed to be moving. Hmmm, So if you fell off a bridge, and landed in the back of a truck drive down the interestate, I'm not sure if they would-be be able to locate you. They would-be cognize wherever you were once you!

first dialed 911, but as your location changes, they power not be able to find you). Supposedly, the 911 operator can pull a refresh, this would-be at least tell them the direction the vehicle is moving. But to locate you patch you're moving, power be more difficult than anyone had expected.

Another problem with many a of the hand-held units, the actual speed of the processors inside them. Most cell phones operate on about 1 to 2 MHz processor speed. Most Smartphones operate anyplace between 30 to 500 MHz. (Most new house computers are in operation between 2 to 4 GHz processor speed, simply to give you an idea). This is wherever the engineers are running into the biggest problem with creating a GPS refresh rate. The processors in all handhelds wish simply have to be quicker than they are today. And like all of our different technolgies, I'm sure this won't be a problem really more longer for the designers.

Hmmm, before long we'll have Pentium 9 cellular and Smartphones running at 8 GHz processor speed! You cognize it's going to move to this, and it's not that far away.
